I have to say that it is an unbeatable combination of location (convenient for Bumrungrad hospital - what we did, and Nana, which is a very happening party district - what a lot of people enjoy) and that despite being in a "hopping" area the room was very quiet and easy to relax in. There is easy access to shopping, entertainment. Skytrain was 5 minutes walk (and Hollis even pointed out how to avoid the busy street) and subway was 8 minutes walk.
Room was very clean, AC worked great. Nice to have a full fridge and a long supply of hot water. Bed was comfortable, having a separate living area with a good size tv was nice to spread out.
Hollis provided a lot of good information and was extremely easy to communicate with. When a small issue of internet access came up, he dealt with it the best he could (as far as we know it was fixed after we left).
I already told Hollis this, when we come back to Bumrungrad hospital for follow up we want to stay at his place.
